This was a recorded talk with Messianic sister Becca Biderman, who lives in Israel, and has been researching the barley intensely. Ideally we want at least two (or ideally three) witnesses to the barley, but as of 2021-02-05 she is the only qualified barley witness that we know of. We hope this will change in the future.
In this video she explains why Aviv barley needs to be medium dough (not soft dough, and not mature), and we talk about the errors that the other barley observers are making.
